Radian per second (rad/s)
The radian per second (symbol: rad/s) is the coherent SI derived unit of angular velocity and rotational frequency. Defined as the angular change of one radian per second, it links rotational movement directly to SI base units. One radian per second equals approximately 57.296 degrees per second or about 9.549 revolutions per minute. It is the standard unit in physics, classical mechanics, control theory, and dynamic modeling.
